Buying property à Bruxelles with a dedicated expert

The Brussels-Capital Region comprises 19 communes with very different price levels, buyer profiles, and urban characters. The following overview is based on Immoweb commune-level data (August 2025) and Statbel transaction records.

• Ixelles / Elsene — Premium urban: One of the most sought-after communes, with prices regularly exceeding €4,237 EUR/m² (source: Investropa / Immoweb, August 2025). Popular with EU professionals, young executives, and international buyers. Dense mix of Belle Époque townhouses, converted apartments, and new-build residences. Strong demand keeps supply tight.
• Uccle / Ukkel — Upscale residential: Approximately €4,001 EUR/m² on average, with the south of Uccle recording price growth of more than 5% recently (source: SmartBlock). Characterised by large family homes, green spaces, and prestigious schools. Attracts families and senior executives.
• Woluwe-Saint-Pierre / Sint-Pieters-Woluwe — Prestigious east: Around €3,957 EUR/m² on average. Houses in this commune frequently exceed €700,000 EUR (source: KBC Brussels, 2025). Quiet, leafy, and well-served by public transport.
• Etterbeek — European Quarter adjacent: Prices regularly exceed €4,000 EUR/m² for both houses and apartments (source: Investropa, 2025). Proximity to EU institutions drives demand from international buyers and investors.
• Saint-Gilles / Sint-Gillis — Trendy and transitional: A popular choice for younger buyers and creatives, with a vibrant neighbourhood feel. Prices are more accessible than Ixelles but rising steadily.
• Schaerbeek / Schaarbeek — Affordable and evolving: Around €3,247 EUR/m² on average (source: Investropa / Immoweb, August 2025). A large, diverse commune undergoing gradual gentrification, offering good value for buyers willing to invest in renovation.
• Anderlecht — Most affordable: Approximately €2,742 EUR/m² on average (source: Investropa / Immoweb, August 2025). The most accessible entry point in the Brussels market, attracting first-time buyers and value-oriented investors.
• Saint-Josse-ten-Noode / Sint-Joost-ten-Node — Compact and central: Around €3,177 EUR/m² on average. The smallest commune in Belgium by area, centrally located, with a dense urban fabric.

The overall average price per m² across all property types in Brussels City (postal code 1000) stood at €3,345 EUR/m² as of August 2025, with apartments ranging from €2,744 to €4,561/m² depending on the zone (source: Immoweb, August 2025).

Buying a property in Brussels follows a structured legal process overseen by a notary (notaire/notaris). The key steps are as follows:

1. Property search and viewings: Identify properties through real estate portals (Immoweb, Zimmo, Logic-Immo) or via a licensed estate agent (IPI-registered). Attend viewings and request all mandatory documents from the seller.
2. Written offer: All offers on Belgian properties must be made in writing. Once both parties sign, the offer becomes legally binding. Buyers should include a financing condition (condition suspensive de financement) to protect themselves if the mortgage is not approved — this clause is typically limited to one month and must be agreed with the seller (source: Investropa, 2025).
3. Preliminary sale agreement — compromis de vente: This is the central legal document of the Belgian purchase process. It is legally binding on both parties from the moment of signature. It identifies all parties, the property, the agreed price, conditions, and the timeline to the final deed. A deposit of 10% of the purchase price is typically paid at this stage and held in the notary's escrow account until the final deed.
4. Mortgage financing: If applicable, the buyer arranges a mortgage loan with their bank. The mortgage deed must also be executed in authentic form by a notary, meaning two notarial deeds are usually required: the purchase deed and the mortgage deed.
5. Notarial due diligence: The notary verifies all legal, urban planning, and cadastral information, requests the mandatory certificates, and prepares the authentic deed of sale.
6. Authentic deed of sale (acte authentique): Signed before the notary, typically within 3 to 4 months of the compromis. The balance of the purchase price, registration duties, notary fees, and all costs are paid at this stage. Keys are handed over upon signing.
7. Registration: The notary registers the deed with the relevant authorities. The buyer becomes the legal owner from the date of the authentic deed.

Public and online auction sales are also possible via biddit.be, overseen by a notary, with an 8-day bidding period (source: KBC Brussels, 2025).

Non-residents and foreign nationals can purchase property in Brussels without restriction — Belgium imposes no foreign ownership limitations. However, obtaining mortgage financing as a non-resident involves more stringent conditions than for Belgian residents.

• Loan-to-value (LTV) ratios: Non-resident buyers typically face LTV ratios of 60% to 80%, compared to 80% to 90% for residents with local income. This means a down payment of 20% to 40% of the purchase price is generally required (source: Investropa, 2025).
• Interest rates: Mortgage rates in Belgium averaged 3.4% in 2024 and fell to approximately 3.5% by November 2025, following ECB rate cuts (source: Expatica, 2025). Non-residents may be offered slightly higher rates depending on their risk profile and the lending institution.
• Income and creditworthiness: Belgian banks require non-residents to demonstrate stable, verifiable income and a sound credit history. Self-employed applicants and those with income from multiple countries face additional scrutiny.
• Required documents for mortgage application: Valid passport, proof of income (payslips, tax returns, employment contract), recent bank statements, and a property valuation report. Non-EU nationals may also be asked for a residence permit or proof of legal status.
• Notary involvement: The mortgage deed must be executed in authentic form before a Belgian notary, in addition to the purchase deed. Buyers without a Belgian identity card will have an account created by the notary to enable participation in the transaction (source: Commissioner Brussels).
• Alternative financing: Buyers unable to secure a traditional Belgian mortgage may explore financing from their country of residence, international private banks, or developer payment plans for new-build properties.
• Tax deductibility: Interest on loans for investment properties remains deductible from real estate income. However, capital repayment tax reductions for new loans taken out from 2024 onwards have been abolished for investment purposes (source: Investropa / Belgian tax reform, 2024).

When buying a property in Brussels, several professional fees apply. Understanding who pays what — and what each professional provides — is essential for budgeting accurately.

• Notary fees: Regulated by the Belgian government on a sliding scale from approximately 0.2% to 4% of the property value. The notary is a public officer who drafts and authenticates the purchase deed and the mortgage deed, verifies all legal and urban planning information, collects and transfers registration duties to the tax authorities, and holds the deposit in escrow. Both buyer and seller may appoint their own notary; if only one notary is used, fees are not doubled — they are shared between the two offices.
• Estate agent commission (seller-side): In Belgium, the estate agent's commission is typically paid by the seller and is not set by law — it is freely negotiable. Market practice in Brussels generally ranges from 2% to 4% of the sale price (source: Choosing the Right Estate Agent in Belgium, 2024). The commission is only payable upon successful completion of the sale, at the time of signing the authentic deed. No advance or hidden costs may be demanded during the mandate.
• Buyer's agent / property hunter: If a buyer engages a property search specialist (chasseur immobilier), that professional is paid by the buyer. Fees vary by mandate and are agreed in advance.
• What the estate agent provides: Property valuation, marketing, organisation of viewings, negotiation support, assistance with the compromis de vente, and coordination with the notary through to completion.
• What the notary provides: Legal due diligence, drafting of the authentic deed, collection and transfer of all taxes and duties, registration of the deed, and issuance of the title to the buyer.

All agents operating in Belgium must be registered with the IPI/BIV (Professional Institute of Real Estate Agents), which provides professional liability and bonding guarantees.
